AUGUST LINDQUIST, OF CHARITON, IOWA, ASSIGNOR OF ONE-HALF TO CHARLES DALIN, OF SAME PLACE.

GRAVE-ALARM.

SPECIFICATION forming part 0f Letters Patent N 0. 500,072, dated June 20, 1893. Application filed February 4,1893. Serial No. 460,953. (No model.)

To @ZZ whom, t ntcty concern:

Be it known that I, AUGUST LINDQUIsT, a citizen of the United States, and a resident of Chariton, in the county of Lucas and State of Iowa, have invented certain new and useful Improvements in Grave- Alarms; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings,wl1ich form a part of this specification.

My invention relates to improvements in grave alarms, whereby persons who are prematurely buried before .life is extinct, can sound an alarm, thus notifying the cemetery officials of the fact.'

The object of my invention, is not only to provide means for sounding an alarm, but also to provide an improved construction whereby fresh air is supplied to the person prematurely buried, whereby life may be sustained until help arrives. A

The invention consists in the novel construction and combination of parts, hereinafter described and claimed.

In the accompanying drawings, Figure 1 is ,an elevation showing agrave supplied with my improved signaling and .air supplying apparatus. Fig. 2 is a cross section. Figs. 3, 4, 5 and G are detail views.

In the said drawings the reference numeral 1, designates a coffin, to contain a supposedly deceased person, which is placed in a grave as usual. Connected with the lid of the coffin, and communicating therewith is a tube 2, which extends a suitable distance above the same, and at its lower end is provided with an opening 3. Also lsecured to the coffin lid is an annular flange 4, of larger diameter than said tube, with which engages the lower end of a pipe 5, which encircles4 and extends somewhat above the upper end of tube 2. This pipe consists of a series of, vertical slats 6, pivotally connected together, so as to be collapsible to enable it to be withdrawn after the coffin has been in the grave such a length of time as will absolutely assure the death of the extends up above.theground,and is provided n with a housing 10,- in which is located a rockbar l2 carrying a bell 13, and also provided with a lever 14, having a cord or rope 15 secured to its end which passes down through the tubes 2, and 8 into the coffin within easy reach of the object contained therein. This housing is provided with a door by which access may be had thereto. A downwardly extending pipe 16 corresponding with pipe 5, is secured to the bottom of the housing.

The operation is as follows: 'When a coin is lowered into a grave, and before the latter is filled in, the tube 2 is connected with the coffin, and the lower end of pipe 5, inserted within the flange 4, and encircling said tube. The tube 8 is then connected with tubes 2 by means of the bayonet joint and the lower end of pipe 16, engages over the upper end of pipe 5. The dirt or soil is then filled in as usual. It Will be seen that the cord 15 extends down into the coffin, and in case the supposed corpse should have been in a trance, and not dead, when regaining consciousness can grasp the cord and sound an alarm. At the same time fresh air will be admitted to the coiiin through the tubes, whereby life may be sustained until help comes. After a sufficient lengt-l1 of time has elapsed, so that it will be positively certain that death has taken place, the housing and the tube 8, can be disconnected fromy tube 2 by giving the same a partial revolution so that theyv may be re moved for duty elsewhere. Also owing to the collapsibility of the pipe 5, it can also be readily removed. By this means, the apparatus can be readily used over and over again.

Having thus described my invention, what In a grave alarm, the combination with a tube adapted to be secured to a coffin, and provided with a pin or stud at its upper end, of the housing having a rock-bar, a bell and a lever, and a cord, and provided with a tube In testimony that I claim the foregoing as having a bayonet-joint engaging with saidi my own I have hereunto affixed my signature stud, and a downwardly extending pipe enin presence of two witnesses. circling said tube, and a collapsible pipe, the AUGUST LINDQUIST;
